A tailboard has a plurality of guide fins arranged relative to the housing so as to receive the chopped materials from the discharge opening to engage onto a guide surface and guide fins of the tailboard construction for spreading of the chopped materials. The tailboard is divided longitudinally into first and second separate tailboard portions, each arranged to receive a portion of the chopped materials and each being adjustable in angle to raise and lower independently of the other so as to provide a different spreading effect on the portion received thereon. Fins on the portions prevent the materials entering the gap. Adjustment on the go from the cab can be provided. | |
